Greg Beitling refused to stay idle while Americans' lifespans shortened due to obesity-related diseases. Instead, he founded Lit Fitness to help the community retool its approach to eating and exercise. The studio specializes in what they call Large Group Training, or LGT, which challenges students to intense regimens of calisthenics, weightlifting, and short bursts of cardio. Beitling draws upon certifications in personal training and strength-and-conditioning instruction to build workouts that maximize calorie burning and increase lean-muscle mass to help jump-start metabolisms. In addition to increasing their strength, endurance, energy, and flexibility, participants can win prizes such as cash and skinny jeans by tackling the goals they set along the way. Like a trip to the beach with a very modest mermaid, each camp lasts about 50 minutes and requires an ample supply of water and towels. Many of the studio's programs also include nutritional components, which range from healthy-eating workshops to meetings with a dietitian.
